Yes i really like the newer 4500 series. I built and flew them before they where 4500 series kits. I believe they used to be DC series. Anyway I learned a lot from my experiences with these great kits. As i got better with them i started adding a motor tube to them. I have been busy with 900 series kits and have not had time for the 4500. I want to go to my first FAC meeting this summer in Geneseo NY. I like to mix photography with model airplanes here is video of a DC series kit https://youtu.be/6wXHscA_ox8
